_Plenius and his Lyrichord._--May I hope to ascertain, through the
medium of your journal, where to look for information on the subject of
the "lyrichord of Plenius," referred to in Rees' _Encyclopædia_, art.
"Basse Fondamentale," as having been "tuned by weights instead of
tension?" The point left in doubt by this, is whether a single weight
was substituted for tension, or whether the different notes in the
musical scale were produced by altering the weight according to the
rules for that purpose.
Was Plenius an ancient, a Middle-Age man, or was he _Herr Plen_, who
latinized his name, as was the fashion a century or two ago?
